I guess I was looking too closely at the “Default behavior” section.The inlining caveat scares me a little, as it would seem to have rather drastic consequences in the future, essentially requiring the worst case scenario, even in the same module, if we want inlining for functions that use enums.<div class=""><br class=""></div><div class=""><br class=""></div><div class="">Jon<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Sep 17, 2017, at 9:09 PM, Rod Brown via swift-evolution <<a href="mailto:swift-evolution@swift.org" class="">swift-evolution@swift.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><blockquote type="cite" class=""><div class=""><br class="Apple-interchange-newline">On 18 Sep 2017, at 9:46 am, Christopher Kornher <<a href="mailto:ckornher@me.com" class="">ckornher@me.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="" style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;"><br class=""><div class=""><blockquote type="cite" class=""><div class="">On Sep 17, 2017, at 5:04 PM, BJ Homer <<a href="mailto:bjhomer@gmail.com" class="">bjhomer@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="auto" class="">Please note that, as proposed, enums are always treated as exhaustive *within the same module*.
